WHIT- Loox PATENTS, INC., or LAs VEGAS, NEVADA, AfcoRroRA'rroN oF NEVADA PRINTING PRESS Heretofore numerous attempts have been made to design a machine of this character which would comply with the requirements of the laws governing the use of such a press and especially With Vrespect to prevent its surreptitious or fraudulent use; the principal object of my invention is to provide a relatively simple, compact, and durable machine embodying the requisite functional characteristics aforesaid, in which impressions cannot be made, Without being accounted for, and in Which `false records or readings of meters cannot behidden, or which cannotbe fraudulently adjusted or tampered with even by custodians of the keys to the press, Without leaving evidence thereof.

Another object of my invention is to provide in such a press a yieldable platen that Will provide an automatic make ready, and thus produce a distinct impression on matter of varying thickness and uneven surface.

Another object vof my invention is to yprovide concealedand inaccessible printing or stamping type at all points of its movement during the action of making 'thel impression and receding same to initial position, thus rendering it impossible to make an impression with the printing type Without registering its movement. I

My inventionis further characterized by providing automatic means for controlling complete movement of t-he printing` mechanism during the descension and elevation of the printing type so that neither movement can be reversed when started until eompleted. Y j A further object of my invention is to provide a means to supply ink to the type of the said press in such a Way that great numbers of impressions Will be made Without manual effort or attention, and for this purpose I have supplied an ink pad attached to and operated by partof the mechanism ofy the press.

A'further object of my invention is to provide `in a press `of the character stated, a recording meter co-operating with theprinting mechanism'adapted to successively count and register vthe total number of impressions made by said printing mechanism, and

View which Will appear more fully as the p description proceeds, my invention resides in the novel combination and arrangement of co-operating elements, claimed and shown in the accompanying drawings forming a part of the present application, `and in Which- Fig. l is a sectional View of the casing from the right. y

In all of the above described figures, like numbers designate like parts. The terms right, left, front, back, etc., refer to the various sides of the machinerelative to the same 4being viewed'from that porti-on termed the front.

In Figs. l, 2, 3, 4, 5, 1and 6, the part designated 2O yis the base plate to Which all of the mechanism of the machine is attached. To base plate 20 are secured bearings 21 in which rotates-'crank shaft 22 to which are connect-ed and Which'actuates-all lof the vari- Y position 26 is securelyfastened to guard boi:

oils parts of the printing mechanism. Said shaft 22, its connecting parts and its relative to said parts, is clearly illustrated in Figs. 2, 4 and 6. Base plate 2O is provided with an opening 22-A at he back end directly over said shaft 22 through which the connecting parts pass; rigidly mounted on the shaft 22 is the guard box arm cam 23, this cam operates underroller 24, secured by pin 25 to guard box arm 26, which guard box arm 26 is rockably suspended underneath and to center bearing shaft'27 which is mounted in bearings 23 wni ch are securely fastened to base plate 20. Guard 29, which cover 30, secured by hinges 3l. A fastening 32 is secured to and holds cover 30 in its closed position. Protecting shield 33 is movably secured by pin 34 to said guard box 29, and to shield 33 isk attache/d type ink pad 35.

Attached to crank shaft 22 and actuated thereby is 'connected printing arm link 37 which isy connected b-y pin 33 to printing arm 39; said printing arm 39 is rockably mounted on center bearing shaft 27; said printing arm 39 is permanently attached to printing member 40 which has mounted on it ink roller 4l by pin 42, which rolls on the 'face of the aforementioned ink pad 35. Per,-

is supplied with a lmanently attached to the iowerface of the printing member 40 yis the type 43 with which to print indicia, the major portion of which type can only be removed from the printing` member 40 by partly dismantling the press, it being necessary to remove center bearing shaft 27 and raise printing arm y the press,

39 out of guard box 29, which gives access to said type 43. Printing member 40 has permanently attached to it, socket 44, in which is mounted removable dater 45, to the lower end of which is attached interchangeable type 46.

Type protecting shield 33 is operated by the movements of printing member 46, which movements are conveyed to the said shield 33 at the top by a tension spring cap 4'? containing tension spring 43, which is held in posii tion by shield tension spring holder 49, which is permanently attached to printing member 40; the movement of the said shield 33 is further actuated on its lower side by Contact between ink roller 4l which is attached t0 printing member40 and ink pad 35, which is attached to the lower section of the said shield 33. The various parts referred Vto in the above description Vare best seen in Figs. 8 and 9. When printing member 40, together with type 43, is in normal position in it is completely surrounded on all four sides by the guard b-oX 29 and is covered on its lower face vby protecting shield33, on top by printing` member 40, thus making it impossible to gain access to the type 43 wit out partially dismantling the press, but perboX arm l mits free use of type 43 in full normal operation of the press.

Y f i l Suspended underneath and toward the rear of lock ratchet arm 102, is control meterY lock 1 trip lever 115, which isA rockably connected to control meter tripconnecting arm 116 by lao pin 117 said arm 116 isloosely connectedto operating lever 118, which is located in front of control meter 78, said operating lever 118 is a part'of ro'ckable'shaft 12() which passes through and has its bearings in sections of both the front andrear parts of control nieter frame 74;,- and permanently secured to shaft 120 is oscillating carriage 119;this os'- cillating carriage119 has" fastenedto'it pawl finger 121 by screws 122,'s`ai`d iinger121rests inra somewhat vertical position and oscillates forward and backward to engage,l in notches 123 in decimal wheels 78-A, 7 8-B, 78-C and 784-1). Trip lever 115 is further suspended at the rear by hanger pin 124 in hanger 125, which is secured by screws 126 to the underside of base plate 20. On control meter 7 8, on the right hand side and secured to the face of and in alignment with decimal wheel 7 8-D, is reset plunger carriage 127, which is rockably mounted on shaft 77, said carriage 127 has operating within it plunger 128, held under tension by spring 129; this Vplunger rests upon the face of decimal wheel hereinafter described, env130 in said wheel '78-C5 127 is Vprovided on top with 78-C, and, as gages in notch plunger carriage Ya bearing'131 containing opening 132 5 vspring 133 is curved at its upward end to engage plunger 128, and its lower end is securely fastened to frame 74; decimal wheel 7 8-D has on its forward side, two pins 134, which engaging against the edges of frame 74, limit the motion of said wheel 7 8-D to the distance between said pins, or one decimal point. When control'meter decimal wheels 7 8-A, 78B, 78-C and 78--D have revolved to the limit ofthe number of impressions to be recorded, which in the use of four of these wheels as limited by pins 134, would indi-v cate one thousand, slots 123 come into align' ment in such a position that the face of iinger 121 vdrops into the said slots 123, thus releasing lever 118, rodr116, trip lever115, which allowsratchet arm 102 under the tension of spring 104 to drop to* and rest upon the lower end of lock ratchet trip arm 107, which arm 107 on its neXt forward move,- ment engages-through its pawl 114 with tooth 106 in arm 102 and forces said arm 102 forward to the limit of its movement, and being engaged with latch 97-A pulls latch 97 -A into the locked position against crank shaft 22, making it impossible to operate the machineuntil the meter has been reset. Side plate 200 has a cavity designed to re ceive a seal containing device having a positioning ring 138, a retaining ring 136 to V145 secured by screws 146 has connected to it shaft 147 riding in bearing plate 148 secured by screws 149. Said bearing plate 148 has another bearing150 for lever 151, secured by pin 152. One end of lever 151 is shaped as at 153to lengage cam 154 keyrelated to shaft 147. Unitary movement is controlled by ratchet wheel 155 key related to shaft 147, and engaged by spring pawl 156 secured by screws 157.k Shaft 147 has key related to it, cam 158, Voperating against lever 159 mounted by pin 160 to hanger 161 secured by screws 162, which is secured at 163 to rod 164, which operates thru opening in plate 20 and connected by pin 166 in opening 132 of bearing 131 of plunger carriage 127.

The action of turning the lock 145 and r0- tating shaft 147 unlocks the locking mechanism ofthe press and resets Vcontrol meter 7 8 to a predetermined number, by the melchanical operation Aof cam 154 first engaging release lever 153 of lever 151 which by lifting trip lever end 115 raises Yratchet arm 102 to apoint where the'tooth 106 is disengaged from the pawl 114, at which point of movement pin 167 operated by shaft 147engages stud 168 on the forward end of ratchet arm 102 and by a rotary motion lifts yand pushes back to its original unlocked position said arm 102, which being connected to latch 971-14 drops the said latch from its engaged or locked position against link 37, thus releasing crank shaft 22 for free operations; said ratchet arm 102 when being moved into locked position is guidedpast pin 167 by spring rguide 169, which is secured by screws 170 to the lower side of plate 95, and said ratchet arm 102 resumes lits original position sideways undertension ofla pin 171 tensioned by spring 172 in carriage 173, which is securely fastened by screws174 to the side of base plate 20; the next continuance step evolved from the rotation of shaft 14,7 by lock 145 is the action, of cam 158 on reset lever arm 159 which pulls down reset connecting rod 164 and resetting the meter to the original predetermined number of the movements. W hen decimal wheel 78-D has been rotated to a point where guide pin 134 rests against the edge of frame 74 and causes said decimal wheel 78-G operating through plunger 128, the plunger carriage 127, to raise plunger carriage 127 and its connections through arm 164, reset lever arm 159, to such a position that its forward end will engage with the cam 158 on shaft 147, thus the operation of rotating shaft 147 reverses the action just described and by pulling down plunger carriage 127 to its original position, automatically resets decimal wheel 7 8-D to the yposition of a predetermined number of impressions to bemade. rhus thecontrol meter 78 maybe set upon completion ofa predetermined number of impressions for another predetermined number by adjustment of saidV may be substituted for the broken seal when iiange 136 `is replaced and automatically locked by the described latches 140.
